“We find that for Psychoanalysis we can expect a recovery rate of 38% after approximately 600 sessions. For Wolpian therapy, we can expect a recovery rate of 72% after an average of 22 sessions, and for Hypnotherapy we can expect a recovery rate of 93% after an average of 6 sessions.”

“A meta-analysis was performed on 18 studies in which cognitive-behavioral therapy was compared with the same therapy supplemented by hypnosis. The results indicated that the addition of hypnosis substantially enhanced treatment outcomes, so that the average client receiving cognitive-behavioral hypnotherapy showed greater improvement than at least 70% of clients receiving nonhypnotic treatment.”
